Highly ludicrous burlesque on the spy melodrama current in the present day, is "An International Sneak," Mack Sennett's latest contribution to the Paramount comedy program. Chester Conklin is featured as Walrus, the agent of "His Imperial Majesty," and his mission is to blow up a munition works. Naturally he bungles the job because a girl detective proves very much smarter than he is. Every scene of the picture is treated with an extremely clever sense of burlesque, even to the manner of deriving suspense while the clock slowly ticks away the minutes to the fatal hour of the explosion. Conklin's ability in this line has never been doubted, and in these two reels gives a thoroughly humorous performance. Ethel Teare is a charming detective, while Billy Armstrong is the terribly mistreated hero.
